# Find acceleration given velocity and mass relationship

### Force, Mass, Acceleration | Zona Land Education

In this lesson, we will learn how to determine the acceleration of an object if the magnitudes of the given information, and your understanding of Newton's laws to determine the acceleration. Use the diagram to determine the normal force, the net force, the mass, and the acceleration of the object. (Neglect air resistance. ). Health · Personal Finance · Home & Garden · Pets · Relationships · Sports · Religion How to Calculate Time and Distance from Acceleration and Velocity In a physics equation, given a constant acceleration and the change in velocity of an Your acceleration is meters per second2, and your final speed is . If we go to mathematical equations, Acceleration =change in velocity/time i.e. reveals personal records for millions of Americans with a simple computer search . Furthermore,there is also a relation between power,mass and acceleration.

The car's average speed is the distance between the two points divided by the time it takes for the car to pass both of them. If the time on the clock at x1 is t1, and the time at x2 is t2, the car's speed s is: Now suppose the car's speedometer is working, and it records two different speeds at points x1 and x2.

Since the speeds are different, the car had to be accelerating.

**Acceleration - One-dimensional motion - Physics - Khan Academy**

Acceleration is defined as the change of speed over a particular time interval. It can be a negative number, which would mean that the car was decelerating. If the instantaneous speed as recorded by the speedometer at time t1 is s1, and the speed at time t2 is s2, the acceleration a between points x1 and x2 is: This average acceleration equations tells you that if you measure the speed at a certain time and measure it again at another time, the acceleration is the change of speed divided by the time interval.

An airplane is flying miles per hour just after takeoff, and it reaches its cruising altitude 30 minutes later, when it is flying miles per hour. What was its average acceleration as it climbed to its cruising altitude?

We can use the acceleration formula derived above. In the imperial system, the unit of force is the pound. Weight is also measured in pounds, so to differentiate mass from force, units of force are called pounds-force lbf.

This gives you the distance traveled during a certain amount of time. If you know any 3 of those things, you can plug them in to solve for the 4th.

### Finding Acceleration

So if you only know v and d, you can't solve for a unless you also know what t is i. The answer given to this question is incorrect. The original answer apparently assumed that the velocity you knew was only the initial one.

In that case that answer is correct as stands. You seem to assume we know both the initial and final velocities. So of course if you know two velocities you know more than if you just know one.

In the formula for distance: How do you calculate for distance then? You'll have to specify this a little more before we can answer. Is there constant acceleration until that velocity is reached, then the acceleration stops? If so, I bet you could solve it yourself.

## Finding Acceleration

Or is there, more plausibly, one of these other situations which also lead to limiting velocities: This applies to objects whose terminal velocities correspond to small Reynold's numbers. This applies to objects whose terminal velocities correspond to larger Reynold's numbers, including typical large falling objects. Some other effect not in the list? I think you're looking too much into my question. I don't understand what 'reynold's numbers' are.
